Review on Hammer.JS by Kadarius Gentry

It's very easy to use, it has great documentation and examples that help you understand how to implement what you need in your project. I think they could improve some aspects of their product like for example adding support for different browsers (Chrome, Firefox etc.). If you have any doubt about implementing hammerjs into your application just contact them or ask questions in their forums. We are using it to build an app that allows users to edit photos by dragging around elements like textboxes, buttons, images etc.
